FAQs
ARB1221 is designed for pendant mounting in Class I Division 2 environments and NEC/CEC compliant installations. Plan for a 1/2 inch luminaire stem, ensure vibration damping via the cushion design, and verify the Vaportight seal with the neoprene diaphragm. Use compatible hardware and follow standard lockout/tagout procedures to minimize wiring exposure during retrofit or new installs. Prepare for mid-weight fixtures in the 16–30 lb range and route cabling to reduce strain on the luminaire stem.
Yes. ARB1221 is specified for a 1/2 inch luminaire stem and pendant mounting. It supports luminaires weighing 16 to 30 pounds and is designed to maintain alignment and secure suspension in hazardous-area environments. The Feraloy iron alloy body provides robust support, while the cushion type helps absorb vibration, improving installation longevity and reducing maintenance calls.
ARB1221 carries NEC/CEC standards compliance and a Class I, Division 2 hazardous rating. Canadian certification references are included in UL documentation, confirming suitability for Canadian hazardous locations. These certifications help ensure regulatory compliance, site safety, and ease of cross-border procurement for projects in North America.
The combination of a compact 6.55 inch length, 4.62 inch height, and 5.21 inch width allows flexible mounting in tight spaces, while the Vaportight cushion reduces vibration-related wear. The 1/2 inch stem and 16–30 lb rating simplify selection and reduce over-engineering. Durable Feraloy alloy and sealed construction lower maintenance costs and extend service life, delivering measurable ROI through faster commissioning and fewer field service calls.
Key concerns include sealing integrity, vibration resistance, and regulatory compliance. ARB1221 addresses these with a Vaportight neoprene diaphragm, cushion-type mounting for vibration dampening, and NEC/CEC Class I Division 2 compliance. Its robust Feraloy iron alloy build supports durability in harsh environments, while the 1/2 inch stem and pendant mounting simplify installation and future reconfigurations.
